TM 5-3895-382-24b.Type 2 and 7BJ EnginesCalculate the difference between the lowestmeasurement and the highest measurement of thefour locations. This difference must not be greaterthan 0.03 mm (0.001 inch) for every 25 mm (1.0 inch)of the radius of the flywheel. The radius of theflywheel is measured from the axis of the crankshaftto the contact point of the dial indicator.Outside Diameter CheckNOTE:The flywheel housing may require removal inorder to perform this runout check.Illustration 102Tooling setup for measuring the outside diameter runout of theflywheel.1.Mount the magnetic base of the dial indicator group tothe flywheel housing or the engine block Position thecontact of the dial indicator on the top of the flywheel inIllustration 102, as shown. Set the pointer of the dialindicator to 0.00 mm (0.000 inch).2.Turn the flywheel. Read the dial indicator for every 90degrees.3.Calculate the difference between the lowestmeasurement and the highest measurement of the fourlocations. This difference must not be greater than 0.30mm (0.012 inch). This dimension is the maximumpermissible distance for the outside diameter runout ofthe flywheel.Electrical SystemSMCS Code:1400Test Tools For The ElectricalSystemMost of the tests of the electrical system can be done on theengine. if the test shows a defect in a component, remove thecomponent for more testing.Before the electrical system is tested, the following conditionsshould exist:The wiring insulation must be in good condition.The wire and cable connections must be clean and tight.The battery must be fully charged.Table 28Tools Needed4C-4911Battery Load Tester18T-0900Ammeter16V-7070Digital Multimeter14C-4911 Battery Load TesterIllustration 1034C-4911 Battery Load Tester.6-98
